Alterations of maternal behaviors of female rats caring for malnourished pups.
The maternal care received by rat pups malnourished by being rotated between lactating females and nonlactating foster mothers was examined. During the 1st 2 weeks after birth there were no differences in maternal care, but during the 3rd week females caring for pups fed only 8 hr daily nursed more and built better nests than females caring for pups fed 16 or 24 hr. These differences in maternal care may interact with and diminish any effects of nutritional deprivation in the pups.
